HP EliteDesk 705 G4 Mini Tiny Key Specs

Something that we wanted to quickly point out here is that these CPUs are Ryzen 2xxx series CPUs. For most of the Ryzen 2000 series, we saw a transition to the 12nm Zen+ architecture. These are still 14nm Zen parts. If you are doing comparison shopping, this is something worth keeping in mind.

HP EliteDesk 705 G4 Mini Performance and Power Consumption

Instead of going through the entire Linux-Bench test suite, we are going to show a few performance and power numbers here to give a general sense of performance. We actually planned to do storage testing, but then we realized that there was a huge variability in terms of what drives could be found in machines.

Python Linux 4.4.2 Kernel Compile Benchmark

This is one of the most requested benchmarks for STH over the past few years. The task was simple, we have a standard configuration file, the Linux 4.4.2 kernel from kernel.org, and make the standard auto-generated configuration utilizing every thread in the system. We are expressing results in terms of compiles per hour to make the results easier to read:

We first wanted to point out that the AMD Ryzen Pro 2200GE generally is 1.5-2x faster than the older HP EliteDesk 705 G3 Mini AMD Pro A10 and A6 options we tested previously. When we looked up the 705 G4 Mini specs we saw these older-generation AMD Pro CPUs as options as well. We should simply note here that the Ryzen CPUs are much better in terms of performance so we are going to suggest those to our readers in this form factor.

7-zip Compression Performance

7-zip is a widely used compression/ decompression program that works cross-platform. We started using the program during our early days with Windows testing. It is now part of Linux-Bench.

While the AMD Ryzen 3 is good here, we have to remember that this competed with the Core i5-6500T of its day, but is now more aligned to the Core i3 CPUs in subsequent generations. As an example, the Core i3-9100T is much faster.

OpenSSL Performance

OpenSSL is widely used to secure communications between servers. This is an important protocol in many serverĀ stacks. We first look at our sign tests:

AMD Ryzen Pro 3 2200GE OpenSSL Sign Benchmark
AMD Ryzen Pro 3 2200GE OpenSSL Sign Benchmark

Here are the verify results:

AMD Ryzen Pro 3 2200GE OpenSSL Verify Benchmark
AMD Ryzen Pro 3 2200GE OpenSSL Verify Benchmark

Price wise, these are now selling for more than many of the systems we purchased with Core i5-8500T CPUs. Those Core i5’s were the result of competition from AMD Ryzen like this system. The impact is that those Core i5’s offer six cores instead of four so they generally offer significantly more performance as you can see here. They are also often less expensive on the retail market.

Something we wanted to touch on here was the performance delta between these two machines. They use the same processor, so we double-checked our test output. The two systems ran within +/- 1.5% so we are calling this a virtual tie between the two. OEMs have different levers they can use so we were not guaranteed that result.

Our key takeaway here is that it is probably better to buy based on the processor model and features rather than hoping that a CPU performs better in one system versus another.

Next, we are going to look at power consumption before moving onto our key lesson learned and final words.

6 COMMENTS

  1. When reflecting on the wisdom “the first lesson learned is to double-check that the units have the features that you want” what I understood is that these machines are difficult to upgrade in the field because they use custom parts. For example a used $30 hd bracket and cable send 10 times more dear than the interchangeable brackets and cables used in many desktop computers.

    These tradeoffs in size, price, performance and maintainability are interesting. I wonder if it will take government regulation to ensure compatibility across brands to avoid excess landfill as required for the plugs on the chargers in the mobile phone industry. Can the power brick of the Lenovo supply this HP mini micro?

  2. One system I suggest you check for this series is the Hardkernel ODROID-H2+. It’s a single board computer but I think it qualifies as a TinyMiniMicro. I just bought one as a desktop replacement because the 8GB Raspberry Pie required too many compromises.

  3. Eric – the brackets do need to be somewhat customized for the chassis, so I can see why.

    Jon – The ODROID-H2+ is a fairly different segment than these. It is a lower power/ performance and was not an ex-corporate desktop PC. With that said, I do love the dual 2.5GbE on those.

  4. There’s what seems to be a small mistake – under the heading “HP EliteDesk 705 G4 Mini Hardware Overview”, the first line is “The chassis itself is a fairly standard design for the earlier Lenovo Tinys.” – surely this is meant to be “standard design for the earlier HP tinys”?

  5. FYI: I had the Ryzen Pro 5 model. It could not handle my 4K at 60 Hz monitor. YouTube would stutter with 4K videos. Even 1080p was not smooth. Took a bit of time to convince the store to take it back.

  6. My office has 2 of these with the Ryzen 5 2400G in them and either 16GB or 32GB RAM. THey are very nice for office desktops as you can use the VESA mount and put them behind your monitor. We have liked them so far and when it comes time for desktops to be replaced, we will probably be going with these for all our employees.
